Chapter 2 — Installation
2.1-BOILER ROOM
The boiler room must comply with all building codes and regulations. An adequate supply of combustion air
and sufficient ventilation are required for safe operation. If the optional direct vent combustion air kit is not
used, ventilation must be provided to meet applicable regulations for air supply.

Clean combustion air is required for optimum efficiency and boiler operation (minimum combustion air 10
cfm per boiler horsepower). Dust and airborne contaminants will adversely effect burner performance.
If conditions dictate, a serviceable filter must be placed at the burner inlet to eliminate airborne contamination
to the burner. If a direct vent air intake is used, the intake and flue venting should be terminated so as to
prevent rain, snow, dust, or debris from entering the intake piping.
Observe proper clearances above and around boiler - see 2.4-.
2.2-LIFTING AND MOVING THE BOILER
The Model CFH boiler is equipped with two lifting lugs extending
from the front and rear tube sheets. These lugs should be used
to lift the boiler.
In order to avoid damage to the unit, lifting or
moving the boiler should only be done by
experienced personnel suitably equipped for
moving heavy equipment.
Note: The boiler should not be lifted by the base, or moved by
pushing, prying, or pulling on any part of the casing.
The boiler must be installed on a non-combustible floor. If the
floor is not level, piers or a raised pad slightly larger in length and width than the boiler base dimensions
will make boiler installation and leveling easier.
The boiler must be installed so that all components remain accessible for inspection, cleaning, or
maintenance. Field-installed piping and electrical connections must be arranged so as to avoid interfering
with removal of the casing panels or with the burner door.
